Your existing thumbnail links will still work, but yes, if you want to change them or add new links, you need to use web locations, instead.

Sorry about that, but once jAlbum included this possibility in the core program, the skin-specific method was deprecated. Having two similar, but not identical, ways of doing the same thing just isn't good software design.

BTW, why is your site using framesets, which are obsolete? This destroys the "responsive" characteristics of the skins you're using, including Gromit.

Most websites aren't created by jAlbum, and they don't have a slides folder or a thumbs folder. The routine is simply looking for a usable image on the page - large enough to use as a good quality thumbnail, and not a background image. It's not expecting to find a jAlbum-created page, so it can't be programmed to look for things that exist only on a jAlbum-created page.

In any case, the skin has nothing to do with this, so take it up with David.
